FRED KELLAR AND WILLIAM ID. NEELY, OF NORTH VERNON, INDIANA.

SEPARATOB.

To all whom it may concern Be it known that we, FRED KnLLAn and WILLIAM D. NEELY, citizens of the United States, residing at North Vernon, in the county of Jennings and State of Indiana, have invented new and useful Improvements in Separators, of which the following is a specification.

This invention relates to separators and it has particular reference to a machine for separating cracked corn into a plurality of products, it being however, understood that the principles of the invention may be applied to the separation of other materials into a plurality of products of different grades.

The invention has for its object to produce a simple and improved machine which at a single operation will separate a staple into a plurality of products of different degrees of fineness.

A. further object of the invention is to produce a machine of the class described of simple and improved construction which will separate from the ultimate products, objectionable material such as dust and the like.

A further object of the invention is to simplify and improve a construction and arrangement of parts constituting the im proved machine or device.

lVith these and other ends in View which will readily appear as the nature of the invention is better understood, the same consists in the improved construction, novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however. understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing,-

Figure 1 is a view in sectional elevation of a machine constructed in accordance with the invention.

Fig. 2 is an elevation of the opposite side of the machine.

Fig. dis a sectional end elevation.

Specification of Letters Patent. Patented NOV. 9, 1920. I

Application filed April 3, 1918. Serial No. 226,488.

F ig. 4 is a similar view of the oppositeend of the machine.

Fig. 5 is a top plan view, parts having been removed.

Corresponding parts in the several figures are denoted by like characters of reference.

The frame structure 15 of the improved machine supports an upper screen cylinder 16 and a lower screen cylinder 17, the lat ter having a transverse partition 18 about midway between the ends thereof whereby it is divided in two sections a and 5 formed of screen fabric of different grades, that of the section a being relatively fine. The partition 18 has in the lower part thereof: an opening 19 establishing communication between the two screen sections.

Extending axially through the screens or sieves 16 and 17 and supported for rotation on the frame structure of the machine are shafts l9 and 20, said'shafts being provided with pulleys or band wheels 21, 22

over which a belt 23 is trained to transmit motion from one shaft to another. Motion may be transmitted from a source of power to either one of the shafts 19, 20, each of said shafts being provided with a pulley 24:, 25 over which a transmission belt may be trained. Said pulleys may be of different sizes in order that the speed may be varied by transmitting the transmission belt from one pulley to the other- The frame of the machine suppors the casing 26 of an aspirating fan, the shaft of which 27 is journaled in bearings 28, said shaft being provided with a pulley 29 that receives motion through the medium of a belt or band 30 from a band wheel 31 on the shaft 19. The fan casing 26 isconnected by a wind trunk 32 with the top portion of a settling chamber 33 having an inclined side wall 34: and a vertical side wall 35 the latter being provided adjacent to its lower end with openings 36 for wh ch doors 37, arranged to close grav tationally, are provided. The straight side wall 35 which adjoins the wind trunk 32 is provided adiacent to its upper end with downwardly inclined deflec ors 38 t at extend in the direction of a vertical deflector 39 which depends from the horizontal top portion 40 of the settling chamber. a

Arranged below the cylindrical screen or feed chute 48.

sieve 16 is a hopper all which receives material discharged through the screen and which discharges such material gravitationally through a chute i2. The screen cylin ler is provided at one end thereof, which convenience will be designated as the outer end, with an inlet or ieedspout over l which is pivotally mounted a valve 50 which.

as shown'in full lines in Fig: 3, may be utilized to obstruct the opening :9 but which may also as indicated in dotted lines in the same figure, be utilized to obstruct communication between the spout or chute eltand the discharge opening 47, thus establishing communication between the duct lfiand the From the later, material be discharged over a spout .51, see Fig.

l, to the inner end or receiving end oi the screen or sieve 17.

'Arranged below the sieve or screen 17 is a hopper 52 having compartments a, b receive material discharged through the screen sections a and b respectively, said compartments a and b beingconnectedwith the settling chamber by'means of a duct 53 having a partition member 54 forming compartments 55, '56 having separate outlets 57, 58 2tl1rough which the products coming from the compartments a and 6' respectivelv will'be discharged.

'Adjacent tothe, tail end of the section b of the screen 17 is a discharge spout 59 whereby the tailings. are delivered into a chute 60, said chute being connected by a duct .or trunk 61 with the top portion of the settling chamber.

For the purpose of. conveying stock through the respective screens or sieves "means are provided "including: arms 62 extending radially fromthe respective shafts 19 and 20, said arms carrying clamping bars 163 provided at intervals with clamp bolts 64:. Glamped securely between each pair of bars 68 are a series of stems 65 each having atits outer end an angularly disposed'wing or blade 66 the outer edge of which will be disposed angularly with respect to the inner circumferenceof the screen, the position of the wings or blades relatively tothe screen being capable of adjustment by turning the stems 65 about their respective axes, thus being easily eifected by slightly loosening the clamp bolts 64 while the adjustment is being efiected. By rotation of the shafts 19, 20 inaterialmay thus be fed in either. direction through the screens or sieves and by proper adjustment of the stems the wings may be variously spaced -from the inner circumference of the screen according to the nature of the material that is to be operated upon. The brush members "formed by the clamp bars63 and related parts are found to be extremely simple'and effective, not only in feeding material through the screens without unnecessarily rubbing the same, thereby producing dust and waste material, but the brushes serving to feed material over the screens without contacting with the latter It is desired to he understood that the screens, including the independent sections of the screens 17, are preterabl mounted in such a manner as to be readily removable in order that screen sections of different grades of materialmay be inserted and used when desired. Such adjustable mounting however,' is well known in the art and-is not herein claimed and it has not been deemed necessary to particularly illustrate such mounting. a

When the valve 50 is in the position shown in dotted lines in Fig. 3, the operation 01 the machine is as follows j Cracked corn will be fed over the chute 4=3t0 the receiving end of the screen 16. As the stock passes over the screenby the action of the revolving brush member, a soft meal will be separated, the same passing through hopper 41 and spout 4-2 to the outlet of the latter where it may be discharged into a sack or other receptacle; The tailings from the screen 16 pass over the chute 44 where vit is immediately subjected to the action of the aspirating fan, bran and lightdust being drawn to the settling chamber from which it may be gravitationallydischarged; The stock passing over the chute a l will be guided over the valve 50, l ig. 3, which is then closed as shown by dotted lines,

through the opening 49 to the spout 51 at the lower'end oi thefeed chute 48 beinginingthrough the compartments a and b of r.

the hopper 52 to the compartments of the duct 53 where aspiration takes place, the grits being discharged gravitationally through the openings 57, 58 at the'lower ends of the compartments 55, 56 of the duct, while the dust' and light materials will be carried. through the trunk 53 to the settling chamber to be gravitationally discharged therefrom. The tailings from the screen section 6 pass over the discharge spout 59 to the chute 60 where aspiration again takes place, the light products passing to the settling chamber while the resultant product being in the nature of pure cracked corn will be discharged through the opening atthe lower end of the chute '60.

is a condition precedent to the operation described, the screen 16 employed will be, for instance, a screen of No. 16 wire, the screen a will be, for instance, a screen of No. 8 wire, and the screen 6 will be, for instance a screen of No. 6 wire.

A different result may be obtained by adjusting the valve 50 to the position shown in full lines in Fig. 3 and employing a screen 16 of No. 16 wire, a screen a of No. wire and a screen 7) of No. 18 wire. The cracked corn first passes over the screen 16. The stock is conveyed over the screen by the brush, taking off fine dirt and dust which falls into the hopper 4L1 and is discharged through the spout 42. The coarse stock tailing out of screen 16 over the chute 44: is subjected to aspiration when it enters the duct 45, the bran and dust passing through the trunk 46 to the settling chamber while the stock is discharged through the opening 47 at the lower end of the spout 4&5. This material is now conveyed to a grinding device such as a grinding bur or roll, being ground into meal which is elevated and delivered into the upper end of the feed chute 18 passing from thence over the spout 51 to the compartment a of the screen 17. where fine meal will be separated while coarse meal will be separated through the screen compartment b by the action of the revolving brush. The two grades of meal will be discharged through the openings 57, 58 of the compartments 55, 56 of the trunk 53, each grade being subjected to aspiration whereby the dust and light material will be carried to the settling chamber. The over-tailings from the compartment 1 2 of the screen 17 will pass over the spout 59 to the chute 60 being there subjected to aspiration whereby the light products are carried to the settling chamber while the relatively heavy material will be discharged at the lower end of the spout 60.

lVhat is claimed, is

1. In a separator, a' frame structure, cylindrical screens supported at diiferent horizontal levels, rotary means to work stock against and move the same longitudinally in the screens, a duct to convey tailings from the discharge end of the upper screen, a duct to convey stock to the receiving end of the lower screen, said ducts being connected through an opening between intermediate portions thereof, and a valve arranged in one position to close the said opening and in another position to guide stock from the first named duct into the second named duct.

2. In a separator, a frame structure, cylindrical screens supported at different horizontal levels, rotary means to work stock against and move the same longitudinally in the screen, a duct to convey tailings from the discharge end of the upper screen, a duct to convey stock to the receiving end of the lower screen, said ducts being connected through an opening between intermediate portions thereof, a valve arranged in one position to close the said opening and in another position to guide stock from the first named duct into the second named duct, a settling chamber connected with the first named duct at a point above the connection between the upper screen and said duct, and an aspirating fan to set up suction in said settling chamber.

3. In a separator, a cylindrical screen, supporting means for the same, feed and discharge spouts supported adjacent to the ends thereof, a driven shaft extending axially through the screen, said shaft having radial arms, side by side, clamp members carried thereby, clamping bolts associated with the clamp members, stems, fitted and movable about their axes between the clamp members, said stems being securely and adjustably held thereby, and wings, carried by said stems.

In testimony whereof we affix our signatures.
